How to Do a Side Lateral Raise

Strengthen your shoulders with this simple move.

This upper-body move targets the anterior and lateral deltoids, two of the three shoulder muscles (along with the posterior deltoids) that power your movements when you're hoisting a carry-on into the overhead luggage bin or putting a stack of plates on a high shelf. Beyond strengthening your reach, this exercise also gives you sleeveless-ready shoulders and visually slims your hips. How's that? "Working the middle deltoids gives the shoulders width and creates definition between the biceps and the triceps," says fitness expert and American College of Sports Medicine and American Council on Exercise-certified personal trainer Keli Roberts. "It also creates great body symmetry: If your shoulders are wider, every-thing below looks smaller."
